which is convergent for \(0<\alpha <1/|\lambda _{\max }|\) , where \(\lambda _{\max }\)  denotes
eigenvalue of largest magnitude of \(\mathcal {A}\) . For many adjacency tensors of interest,
\(\lambda _{\max }\)  is real and positive. Conditions under which this is the case are
discussed by Qi and Luo [1]}. For tensors of order 4, the eigenvalue
\(\lambda _{\max }\)  can be computed as an eigenvalue of a matrix using the relation of Remark
REF . The choice of \(\alpha \)  affects the \(\delta \) -effective diameter of the tensor
function (REF ). This is discussed for the matrix resolvent in [2]}.
